The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.Earth’s natural greenhouse effect Earth’s tempe rature begins with the Sun. Roughly 30 percent of incoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70 percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbed solar energy heats our planet. As the rocks, the air, and the seas warm, they radiate “heat” energy (thermal infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbed by water vapor and long-lived greenhouse gases such as carbon dioxide and methane. When they absorb the energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in all directions. The energy that radiates back toward Earth heats both the lower atmosphere and the surface, enhancing the heating they get from direct sunlight. This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.What has scientists concerned now is that over the past 250 years, humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly by burning fossil fuels, but also from cutting down carbon-absorbing forests. Since the Industrial Revolution began in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methane levels have increased 148 percent.II.拓展提高书面表达如何解决全球变暖是我们全人类共同面临的一个难题。

全球气候变暖是一种“自然现象”。人们焚烧 化石矿物以生成能量或砍伐森林并将其焚烧时会产 生二氧化碳等多种温室气体。这些温室气体对来自 太阳辐射的可见光具有高度的透过性，而对地球反 射出来的长波辐射具有高度的吸收性，能强烈吸收 地面辐射中的红外线，导致全球气候变暖，也就是 常说的“温室效应”。全球变暖会使全球降水量重 新分配、冰川和冻土消融、海平面上升等，既危害 自然生态系统的平衡，更威胁人类的食物供应和居 住环境。
Sophie Armstrong wrote the magazine article. The name of the magazine is “Earth care”.
2.What are the names of the three scientists mentioned in the article?
They are Dr. Janice Foster, Charles Keeling and George Hambley.
3.What do they think about global warming?
Do they agree with one another?
There are some very different attitudes among scientists towards this issue. Some think the effects will be terrible,
Now, let’s enjoy a short video about global warming. It’s funny and grieved.
We depend on energy to do many things in our daily lives. For example, energy lights our cities and heats our buildings. Make a list of things that use energy in your home, in your school, or any other places you can think of.
